vSpecification of Letters Patent. Patented Dec. 2, 1919.

Application filed April 4, 1918. Serial No. 226,696.

To all whom it may concern Be it known that I, HUGH PURDY, a sub ject ofthe King of Great Britain and Ireland, residing at Belfast, Ireland,have 1nvented certain new and useful Improvements Relating to IVindows,of which the following is a specification.

This invention relates to windows of the class having a sliding sashadapted to open inward and its object is to provide an improved windowof this class which will be perfectly weather proof when closed whlle itwill also be capable of being opened inwardwhen required.

Under my invention, in order to give a finished appearance to thewindow, a sliding head is provided in connection therewith to fill inthe top of the sash when in the closed position, the head having beveledend surfaces and being so arranged that, when the sash is raised, it iseasily moved upward therewith so as to allow of the sash opening inwardand when the sash is closed and lowered on to the rabbet of the framebottom, the sliding head drops down again and closes up the openingwhich would otherwise be left above the sash top.

The sliding stile may be raised by direct lift, or by lever action, orotherwise, and by any suitable device or devices.

The invention can be applied to single or double sashes.

In order that the invention may be clearly understood I have hereuntoappended explanatory drawingsshowing the invention applied to 'a singleinwardly opening sash.

Figures 1 to 4 show a wooden sash.

Figs. 1 and l show the four corners of the window in front elevation.

Fig. 2 is a cross sectional view on the line 22, Fig. 1*.

Fig. 2 is a view showing the window raised for ventilation purposes.

Fig. 3 is a sectional plan view on the line 3-3, Figs. 1 and 1 Fig. 4 isa small view showing the whole window in front elevation.

Figs. 5 to 8 show a metal sash.

Figs. 5 and 5 show the four corners of the window in front elevation.

Fig. 6 is a cross sectional view on 6-6, Fig. 5

Fig. 7 is a sectional plan view on the line 77, Figs. 5 and 5*.

Fig. 8 is a small view showing a whole window in front elevation.

the line tially the same in 'both the examples shown and in thedescription hereinafter set forth 7 the reference letters used may referto either the wooden window sash (Figs. 1 to 4) or the metal window sash(Figs. 5 to 8).

Referring to the drawings a is the window frame, 5 the outer casing andc the inner casing. (Z is the jamb lining. The opening sash f of thewindow is hinged to the sliding stile g by means of hinges i and thesliding stile in Figs. 1 to 4E, has projections g and 9 or equivalent,engaging in corresponding grooves in the sash frame and inner casing 0so as to exclude wind and rain, while in the modification shown at Figs.5 to 8 the sliding stile g has projections 9 and 9* engaging incorresponding grooves in the outer casing and inner casing respectively.A rabbet joint is also formed between the bottom 7' of the sash f andthe sill at of the window frame. The sides and top of the sash f areprotected by the outer casing boards 5 and at the opening side of thesash I provide (in the case of the wooden sash) a bead or projection fengaging in a groove 0 in the inner casing 0.

' Above the sash f I provide a space Z with sloped surfaces Z and Z atthe ends thereof and in the space Z I place a sliding head m which'fillsin the space which would otherwise be left above the sash top when thesash is in the closed position. The sliding head m is so beveled at itsends that the sloped surfaces Z and Z cooperate therewith to cause it toslide easily upward when the sash is raised so that when fully raisedthe sash can open freely inward over the top of the sill a When the sashis closed the sliding head m drops down again by gravity action.

The sliding stile 9 may be raised in any suitable way. In the exampleshown, Figs. 1 to 4:, the stile is raised by providing a rack 0% adaptedto cooperate with a toothed lifting lever 0, which is turnably supportedon a pin 0 secured to the jamb lining d.

This sash has the advantage of being perfectly secured and at the sametime giving ventilation in rooms where it is not suitable to leave thewindow open.

Having now fully described my invention, what I claim and desire tosecure by Letters Patent is In a window structure of the characterstated with hinged and sliding sash, a windowfrainehaving-inclined'suffaees atthemOVementS Of'the seshfsubstantiallyas set '7 7 top thereof, a sliding head carried in-the forth. 10'
